The actual product may differ slightly from the image.
Elbow DILO tube unions can be used for 90° angles. Angle unions are available with weld-on ends for applications where highest vibration resistance is required. They are also available with weld-on end and Whitworth screw-in thread.
Throttle-free swivel unions allow positioning of the weld-on end as per your requirements. Thus, any tubing can be established, no matter how complex they are.
Temperature resistance of all unions from -270 °C up to +500 °C, depending on the material used.
